Truss or tension rod both have the same foundation needs, unless you're sinking an end post into the ground (unnecessary).A “truss” design seems to make the foundation less important.
...
Can I eliminate the top tube, replace with angle iron and a wood cap?
If what I’m reading you guys are posting it seems that my be an option.
Either (right side post in drawing) there needs to be a member between the two upright end posts that can stand your load in compression, or (left side post in drawing) a diagonal brace serving the same purpose (can still have a light handrail).
Neither affects the foundation; all load on the foundation is as it was when you started this thread. Anchor one end of the bridge, maybe both ends (one side have slotted anchors? idk), with some way to account for thermal expansion of the bridge and it flexing under load.
